SPLIT-TYPE EMERGENCY STARTING DEVICE, WITH INTELLIGENT PROTECTION DEVICE, FOR BATTERY PACK

摘要

Disclosed is a split-type emergency starting device, with an intelligent protection device, for a battery pack, comprising: at least two sets of battery packs; a battery voltage measuring module for detecting a voltage between a positive electrode and a negative electrode of each battery in each battery pack and outputting a corresponding voltage value; a short-circuit protection module for protecting a battery when an output of each battery short-circuits; a first switch module arranged between each battery pack and an external charging input, and a second switch module arranged between each battery pack and a battery external output; and an MCU for receiving the voltage value and respectively outputting a first control signal and a second control signal to the first switch module and the short-circuit protection module according to a relationship between the voltage value and a pre-set voltage value. By means of split-type input and output protection for a battery, when the battery is charging and discharging, each battery pack is in an independent secure state, thereby preventing the use of an entire battery being affected due to one battery pack being damaged; and the structural design is simple and the costs are low.
